Description

  The present invention relates to an adapter for coupling a peripheral device such as a bag for collecting excreta to the anus or perianal stoma, and an adapter for coupling a peripheral device to the anus to provide fluid tight fixation. The present invention relates to a device and a kit including an adapter and a peripheral device.

  Incontinence is a common problem among people who are paralyzed, such as paraplegics or paralyzed limbs or comatose patients. In addition, bedridden patients are generally unable to go to the toilet by themselves, and there is not always someone around to help. It is therefore necessary to collect excreta from such patients and prevent them from leaking out. In particular, in the case of a person suffering from diarrhea or a coma person, it is important that the excrement can be collected very frequently, and that the nurse does not receive discomfort from such a person.

  Other solutions for collecting such excreta have been tried to meet these needs and another device has been obtained.

  One such device is a “drainable waste collector” made by Hollister. This is a bag that is attached around the anus where it can accept excrement.

  However, since this type of bag needs to be changed frequently, the place where the bag is attached increases the risk of causing skin irritation. Thus, there remains a further need to allow excrement collection while avoiding such frequent exchange of bags.

  U.S. Pat. No. 4,784,656 generally includes a gasket that engages a seal in a region substantially proximate to the eyelet or anus of the wearer to form a fluid tight seal therebetween, and is coupled to the gasket. A conduit providing a path through which waste received from a small hole or anus of the person passes, and a disposable receptacle detachably coupled to the conduit for collecting and discarding the waste received from the conduit An excrement receptacle is disclosed.

  However, since the patient is often bedridden, for example, still in a wheelchair, the patient often sits or lies on a member of the device. Rigid devices or parts of such devices tend to be uncomfortable for the patient and can even cause ulcers and other types of inflammation.

  In one aspect, the present invention provides an adapter for connecting a user's anus or stoma around an anus to a peripheral device, and a flexible attachment plate having a first through hole and extending from the first opening to the second opening. A flexible tube and a first flexible coupling plate having a second through-hole, and the flexible tube is fixed to the flexible attachment plate in the peripheral area of the first opening and The user's anus or perianal area is secured to the first flexible coupling plate in an area surrounding the two openings and allows fluid communication from the first through hole to the second through hole via the flexible tube An adapter for connecting a stoma to a peripheral device is disclosed.

  The present invention provides an adapter that allows a flexible coupling between the adapter and the peripheral device when the adapter is coupled to the flexible coupling plate of the peripheral device. The present invention provides a connection in which a flexible connection that conforms to the body to which pressure is applied in use provides more comfort for the user and a portion or the entire adapter, peripheral device and / or between them. It has the advantage of reducing the risk of developing ulcers for a bedridden user on the joint.

  In the following description, the term flexibility should be interpreted as relating to the human body. The flexible attachment plate can be applied to the shape around the anus, and there is also a fluid tight seal between the area around the anus or perianal stoma and the flexible attachment plate and between the peripheral device and the flexible coupling flange. Follow the movement in this area while providing. The flexible tube expands to allow excretion to pass from the anus to the peripheral device, and can be airless (collapsed) when the buttocks deform or move. The flexible coupling flange is flexible to conform to the body shape when the user sits or lies down or when an external force is applied. Thus, the different flexible parts of the adapter match the body shape in different situations.

  Generally, flexible members of this type are known to those skilled in the art, and here such materials can be selected from those presented in the present invention as disclosed to those skilled in the art. For example, the flexible adhesive plate can take the form of a hydrocolloid additive formed on a polyethylene backing layer. This type of form is known, for example, as an additive ostomy device. The flexible tube can be formed from, for example, a polymer foil. The flexible coupling flange can be made of polyethylene having a thickness of 0.5 to 3 mm, for example. This type of coupling flange is also known, for example, as an additive coupling arrangement in ostomy equipment.

  It should be understood that the adapter must meet certain requirements and criteria because it is for coupling the user's anus or perianal stoma to the peripheral device. Such a requirement is that it is generally accepted that the materials used for the adapter are of medical grade and therefore are in contact with the human body for a long time.

  The through hole is generally elliptical in shape, but the hole may have other shapes, for example circular or triangular.

  The flexible tube can be secured to the flexible attachment plate and the flexible coupling flange in a number of different ways. This fixation can be performed, for example, by gluing or welding the elements together in a fluid tight manner.

  Furthermore, the flexible tube can be formed in a number of different ways depending on the material, the manufacturing method, and the like. In one simple embodiment, the tube is a hollow cylinder formed of a polymer, and in another embodiment it can be formed as a hollow cylinder having an inclined surface, i.e. having a conical surface. In yet another embodiment, the tube may be formed in two conical hollow cylinders welded together. The function of the tube of the present invention is mainly to provide a path for fluid communication between the first opening and the second opening and to be a spacer for separating the flexible attachment plate and the flexible coupling flange. Must understand.

  In one embodiment of the adapter according to the invention, the length of the tube varies along the circumference of the tube. In this configuration, when the flexible attachment plate is attached around the anus, and the tensile force is applied on the first flexible coupling plate, the tensile force is transmitted through the shortest distance of the tube. Demonstrate the effect that is directed to. Therefore, by orienting the attachment plate and the flexible tube, the tensile force is advantageously directed to the region of the flexible attachment plate, and both are attached to the skin region with little influence on the tensile force. It should be noted that in such a situation, the tensile force is a force applied in a direction away from the adapter when it is attached to the human body. It is also understood that the tensile force is generally directed from the flexible adhesive plate to the flexible coupling flange.

  When referring to the length of the tube, it should be understood that it is the length between the attachment plate and the connecting flange along the surface of the tube. Thus, the same tube, each in the airless position and in the unfolded position, still has the same length in both positions.

  It should be understood that the periphery of the tube generally corresponds to the periphery of the tube, whether the tube is circular, square or otherwise in cross-sectional shape.

  The tensile force is not always directed perpendicularly from the flexible adhesive plate or perpendicular to the flexible coupling flange. Therefore, in order to allow tolerances in the direction of the tensile force and prevent the tensile force from being distributed to undesired areas of the skin, the difference between the maximum and minimum lengths in one embodiment is at least 5 mm, Preferably it is at least 10 cm.

  In one embodiment of the adapter according to the present invention, the first through hole is eccentrically disposed in the attachment plate and defines first and second distances of the attachment plate extending along opposite sides of the first through hole. ing. This configuration has the effect of changing the distance from the center of the through hole to the periphery of the attachment plate around the attachment plate, and thereby forming a region with a larger attachment surface than other portions.

  A larger attachment area is advantageously provided in this response for another reason. For example, the skin surface around the anus is larger than elsewhere, and thus can accept a larger application area, and the larger application area distributes the force over the larger skin area, thereby reducing the desired area. It becomes possible to distribute a high tensile force not to a specific area.

  In addition, an attachment area having a smaller area is provided to tightly secure the flexible attachment plate around the anus to provide a fluid tight seal.

  In a preferred embodiment of the adapter according to the invention, the symmetry axis of the attachment plate lies in the plane of the attachment plate and the symmetry axis intersects the central axis of the first through hole. This arrangement provides an attachment plate with corresponding attachment areas on opposite sides of the axis of symmetry having corresponding attachment characteristics.

  In addition, the perineum of the female midfoot region typically has a distance of 1.7-3 cm, and the male has a corresponding distance between the anus and scrotum of 3-7 cm. Thus, in one embodiment of the adapter according to the invention, the first distance is between 1.7 and 3 cm, and in another embodiment the first distance is between 3 and 7 cm.

  In addition, for children and infants, this distance is even shorter, generally 0.5-1.7 cm.

  However, there is a larger skin area suitable for attaching an attachment plate to the sacral area of the intermediate heel area. Thus, in one embodiment of the adapter according to the invention, the second distance is at least twice the first distance.

  When a flexible attachment plate is attached around the anus, the plate must be able to be bent into a number of different shapes to accommodate the user's movements and to apply to different physiological functions. In many situations, the flexible attachment plate may even be folded approximately 180 degrees, so that the backing of the flexible attachment plate (ie, the side not attached to the skin) is folded onto the plate itself. In such situations, the flexible attachment plate may contact the flexible coupling flange or peripheral device, as the peripheral device may detach from the adapter, which may pose a risk of spillage being scattered to the surrounding area. It is desirable not to be in a state.

  Therefore, in order to reduce this risk, the length of the tube is perpendicular to the central axis of the first through hole and is more convenient than the distance from this central axis to any point on the periphery of the flexible attachment plate. Is getting longer.

  In general, the attachment plate is folded around this axis of symmetry. Thus, the length of the tube is advantageously longer than the longest distance from the axis of symmetry to any point on the periphery of the flexible attachment plate.

  In another aspect, the present invention discloses a peripheral device for coupling with an adapter as previously described. The peripheral device includes at least one second flexible coupling plate for adhesively coupling with the first flexible coupling plate of the adapter, and a third through hole provided in the at least one second flexible coupling plate. I have.

  This configuration provides a peripheral device that facilitates coupling with an adapter as described herein, and provides a flexible coupling that easily matches the shape of the human body when the peripheral device is coupled. Generally, this flexible coupling is provided by a flexible coupling flange and a flexible coupling plate, the flexible coupling plate comprising an adhesive that is attached to the flexible coupling flange by a fluid tight flexible coupling. ing.

  In addition, different peripheral devices are used, while adapters are placed around the anus to prevent skin irritation caused by the replacement of different peripheral devices.

  It should be understood that the same considerations for the selection of flexible materials and the selection of materials suitable for use on the human body must be taken with respect to peripheral devices such as adapters as described above. For example, in order to removably attach the flexible coupling flange onto the adapter, the flexible coupling plate can be made with a hydrocolloid or acrylic additive.

  Many different types of peripheral devices can be coupled to the adapter, each serving a different purpose. In the following, different types of structures suitable for execution on this type of peripheral device will be described. These structures may be executed separately on different peripheral devices or in a plurality of different combinations providing peripheral devices for a number of different purposes.

  Furthermore, the peripheral device described here is adapted to be able to be coupled to an adapter as also described herein, i.e. to provide a flexible coupling, but with a separate adapter. It should be understood that the application of the same structure to a peripheral device having a combined structure is within the scope of this specification.

  One typical function of the adapter and the peripheral device coupled to it is to collect excreta from the anus, so in one embodiment according to the invention the peripheral device comprises a flexible bag, in which Is provided in the first half of the bag. This configuration allows the excrement to be contained in the bag and is removed from the adapter and discarded when the bag is full. A new bag is then coupled to the adapter as needed.

  In one embodiment of the peripheral device according to the invention, a discharge port is provided in the second half of the bag. Thus, the peripheral device can be easily emptied when the bag is full.

  In order to prevent the excretion of waste into the adapter and avoid the risk of clogging or irritation on the exposed skin around the anus, at least one check valve is attached to at least one of the flexible coupling plate and the bag. Located between the two sections, fluid allows downstream flow from the flexible coupling plate to at least one section of the bag, but prevents upstream flow.

  In one embodiment that is simple to manufacture and very reliable, the at least one check valve comprises a flexible wall extending to the first side of the bag and the second side of the bag, the flexible The upstream end of the wall is secured to the first side of the bag in a fluid tight manner along the entire extent of the first side of the bag in a direction transverse to the flow, and the downstream end of the flexible wall crosses the flow. Partially secured to the second side of the bag in a fluid tight manner along a range of the second side of the bag in the direction.

  In another embodiment of the peripheral device according to the present invention, a filter is provided in the peripheral device to allow the release of gas from the device. The main effect of this type of filter is to prevent the bag from rupturing due to gas generation and causing discomfort to the user, and it also includes an adapter and a peripheral attachment to establish pressure inside. Yes.

  With an understanding of the present invention, those skilled in the art can use many different types of filters known in the art. For example, a filter known as an ostomy device can be used. For example, there is a filter device disclosed in EP 0981311.

  In certain situations, we are interested in monitoring the perianal area. This is for suspicion of skin inflammation in this area, or to monitor excretion from the anus. For this type of monitoring purpose, the peripheral device includes a transparent section disposed opposite the flexible coupling plate.

  In another situation, it is of interest to insert an insert into the peripheral device, adapter and / or anus. This is, for example, a thermometer or a device for taking a sample of excrement. Accordingly, the peripheral device can include an access port that allows entry into the peripheral device.

  In one embodiment, the peripheral device further comprises an absorber cap that can absorb fluid. This type of absorber cap can be provided in a bag, such as the bag described above, to absorb some of the liquid from highly fluid waste.

  In another implementation, this type of absorber cap covers a third through hole in the flexible coupling plate. This configuration allows for a small peripheral device and allows some movement without the user being bothered by a large peripheral device as the absorbent cap absorbs waste.

  It should be understood that many other possible combinations and modifications of peripheral devices can be provided within the scope of the present invention. Thus, in one simple embodiment, the flexible coupling plate is simply covered with a cap to prevent fluid from leaking through the through holes in the flexible coupling plate.

  The adapter and peripheral device have been described so far as two separate units, but they are subordinate to each other in order to operate properly. Accordingly, in another aspect, the present invention discloses a kit for excrement disposal comprising an adapter as previously described and at least one peripheral device as previously described.

The present invention will be described in more detail with reference to the drawings.
1 and 2 show an adapter for coupling a user's anus or stoma around the anus to a peripheral device (not shown) in a fluid tight seal.

  The adapter comprises a flexible adhesive plate 2 formed of a hydrocolloid adhesive disposed on a polymer backing layer, and a flexible tube formed of a polymer film such as a so-called barrier foil that is permeable to moisture and odor. 3 and a flexible coupling flange 4 made of polymer.

  A first through hole 5 is formed in the flexible attachment (bonding) plate 2, and a second through hole 6 is formed in the flexible connection flange.

  The first end 7 of the tube is fixed to the flexible adhering plate around the first through hole by the first weld 8 and the second end 9 of the tube around the second through hole is a flexible coupling flange. It is being fixed to the 2nd welding part 10.

  Thus, the fluid path is in the tube through the first opening 11 defined by the first end of the tube through the first through hole, and through the second opening 12 defined by the second end of the tube. It is possible outside and through the second through hole.

  When a flexible attachment plate is used, the plate is attached around the anus and excretion is allowed to pass through the first through hole.

  The adapter is shown in its collapsed state in FIGS. However, when unfolded, the lengths of the flexible attachment plate and the flexible coupling flange tube extend beyond the buttocks and the flexible attachment plate is secured around the anus. In other words, the flexible tube functions as a spacer with the flexible attachment plate and the flexible coupling flange tube, and allows the flexible coupling flange to be disposed at a distance away from the human body.

  FIGS. 3 and 4 show a first embodiment of a peripheral device 20 according to the invention that can be attached to, for example, the flexible coupling flange shown and described with reference to FIGS.

  Peripheral device 20 is formed of a bag 21 made of a thin polymer film. This bag is formed by welding the first polymer sheet 22 and the second polymer sheet 23 together along the edges of both. A flexible coupling plate 24 is provided on one half 21 'of the bag, through which a through hole 25 is provided to provide access to a compartment 26 of the bag. The bonding plate forms a hydrocolloid-attached plate provided on a polyurethane backing layer.

  Therefore, the peripheral device 20 collects excrement from the adapter when the adapter attachment plate is attached around the anus. Peripheral device 20 is generally attached to the adapter by aligning the through hole of the flexible coupling flange with the through hole of the flexible coupling plate and pressing both.

  The peripheral bag further includes a gas filter 27 to provide communication with the exterior of the bag through holes 28. This configuration, for example, allows the stored gas to escape so that the bag does not swell and unpleasant to the wearer. Such filters are generally known, for example, from ostomy devices, and are formed so as to block only the release of gas and not liquid. In addition, many such filters have an integrated deodorizer to neutralize the odor of the emitted gas. However, when the person skilled in the art recognizes that this type of filter can be used here, many different types of gas filters can be used, and this is known in the art.

  Three check valves 29, 30, 31 are further provided in the bag. The excrement accommodated in the bag is prevented from returning to the adapter through the through hole of the flexible coupling plate.

  The check valves are each formed of polymer film walls 32, 33, 34 and are fixed inside the bag by welds 35, 36, 37, respectively. Each weld has a first weld section 38, 39, 40 and a second weld section 41, 42, 43, the first weld section securing the respective wall to the first polymer sheet 22, and the second A welded section secures each wall to the second polymer sheet 23.

  Furthermore, when the weld section is viewed in terms of flow, i.e., flow flows from the flexible coupling plate disposed on the first half 21 'of the bag 21 toward the second half 21 "of the bag. A first weld section is provided upstream and a second weld section is provided downstream, the second weld section further interrupting in at least one zone provided with openings 44, 45, 46. Has been.

  Thus, when excrement flows in the downstream direction, the polymer film wall, the second polymer sheet, and the second weld section function as a funnel and pass through openings 44, 45, 46 in the second weld section of excrement. Allow flow. However, if the waste already collected in the bag begins to flow upstream, the polymer film wall will fold against the surface of the second polymer sheet, thereby preventing the flow of waste to the opening. Is done.

  A discharge port 47 is provided in the second half of the bag 21. The discharge port easily empties thin waste, which causes the peripheral device 20 to wear over time. In addition, the exhaust port is also used as an extra outlet for venting gas in the event of excessive flatulence that can load the filter 27.

  A second flexible coupling flange 48 is disposed on the second polymer sheet 23 opposite the flexible coupling plate disposed on the first polymer sheet 22. This second flexible coupling flange allows additional peripheral devices to be secured. If additional peripheral devices are not secured, a cover (not shown) is attached to close the through hole 49 of the second flexible coupling flange.

  When attached to the adapter, the peripheral device typically abuts the user's skin. In order to provide increased comfort to the user, a nonwoven sheet 50 covers the first polymer sheet 22 on the side of the peripheral device that faces the skin when the peripheral device is used. Other materials than the non-woven material can be used as long as they are suitable for abutting against the human skin for a long time.

  5 and 6 show a second embodiment of the peripheral device 60, in which a bag 61 having a different shape extends from the flexible coupling plate 62. The bag is ergonomically formed with two flaps 63, 64 across the direction of flow, this direction being from the flexible coupling plate to the outlet 65. The flap extends below the buttocks and conforms to the human body shape to make the bag more comfortable for the wearer compared to many other known bags that collect excreta.

  The outlet 65 is formed as three sections 66, 67, 68 provided with three stiffeners 69, 70, 71, respectively. The outlet 65 can be easily sealed by folding the three sections together. The two Velcro® flaps 72, 73 lock these sections in place.

  The bag is further provided with a gas filter 74, and an opening 75 in the bag allows gas such as stagnant gas to pass therethrough, thereby preventing the bag from inflating and causing inconvenience to the wearer. It does not give a pleasant feeling, and even avoids the bag being removed due to excessive pressure.

  Two nonwoven sheets 78 and 79 cover the sides of the bag, and the sheets are formed of two transparent polymer sheets 76 and 77 that are welded together. In the nonwoven fabric sheet 78, the slit 80 is provided on the opposing side part of the flexible coupling component (plate), and the contents of the bag can be visually inspected from below the transparent polymer sheet 77.

  In order to prevent backflow through the flexible coupling plate 62, a check valve 81 is provided in the bag. This check valve is formed by a polymer film wall 82. The polymer film wall is fixed by three welds 83, 84, 85 to the same polymer sheet 76 to which the flexible bonding plate is bonded. The three welds are interrupted by three openings 86, 87, 88. Therefore, a funnel-shaped check valve as described in the first embodiment of the peripheral device is provided.

  In another embodiment of the peripheral device, as shown in FIGS. 7 and 8, the peripheral device has a through hole (reference numeral 49 in FIG. 4) in a flexible coupling flange (reference numeral 48 in FIG. 4 and reference numeral 4 in FIG. 2). And a cap 90 for sealing 12) in FIG.

  The cap is formed from a flexible bonding plate 91 formed from an adherent hydrocolloid disposed on a polyurethane backing layer welded to a polymer cover sheet 92. The cover sheet covers the through hole in the flexible coupling plate 93.

  FIGS. 9 and 10 show a second embodiment 100 of a cap for coupling to a flexible attachment flange, which can release a gas such as a stagnant gas.

  Cap 100 is formed of a flexible bond plate 101 formed of an adherent hydrocolloid disposed on a polyurethane backing layer welded to compartment 102. The compartment is defined by two polymer side walls 103, 104 and a circular polymer wall 105 secured to the periphery of each side wall.

  An absorber 106 for absorbing liquid in the compartment and a gas filter 107 communicating with the exterior of the compartment through a hole 108 in one of the polymer sidewalls 104 are provided.

  11 and 12 show another embodiment of the peripheral device having the shape of the interface unit 110. FIG. The interface unit is formed of a flexible bond plate 111 made of an adherent hydrocolloid disposed on a polyurethane backing layer. The backing layer is welded to the polymer disc 112 and includes a first through hole 113 that is aligned with and in communication with the through hole 114 of the flexible coupling plate.

  An access port 115 covers the first through hole 113 and is welded to the polymer disk on the opposite side of the flexible coupling plate. The access port includes a canal 116 that communicates the first and second through holes.

  Therefore, in use, the anus can be accessed via the canal in the access port. Therefore, a thermometer can be inserted to measure the user's body temperature or a sample of excrement can be taken. For example, many other surgical devices can be inserted through the canal.

  The above-described embodiments are merely illustrative, and many other embodiments and combinations of the above can be envisioned within the scope of the present invention.

  It should be noted that as explained so far, the flexible coupling is provided when the flexible coupling flange and the flexible coupling plate are coupled together. However, as described above, the flexible coupling plate is sticky and attaches the coupling plate to the flexible coupling flange. It is also within the scope of the present invention that the flexible coupling flange also has attachment properties on itself and / or that the attachment properties are provided on the flexible coupling plate.

  In addition, many different materials other than those described herein can be used to manufacture adapters and peripheral devices as long as they are suitable for use in contact with the human skin.

"Example 1"
In one embodiment, the first flexible coupling plate and the second flexible coupling plate are provided as corresponding parts in an Easyflex coupling manufactured by Coloplast A / S. be able to. This coupling was previously used together for the ostomy substrate corresponding to the first flexible coupling plate and for the ostomy pouch corresponding to the second flexible coupling plate. . The Easyflex coupling structure is provided as a flexible coupling plate and attached to each other. Compared to mechanical coupling, this provides much more comfort and can follow the body contour of the user, such as a bedridden person.

  To understand the advantages, a comparative test was performed to illustrate the flexibility characteristics of the attachment coupling (ie, the first and second flexible coupling plates provided as an eaflex coupling plate) versus the mechanical coupling. The coupling according to the invention was tested with varying flexibility.

  The coupling was tested by applying the same excursion with respect to the height of the coupling, and the load force was measured corresponding to the excursion.

  Coupling dimensions are selected such that the output is a similar center hole diameter through which it can be collected.

  The test is a standard test, ASTM D790-96a. This test uses a three-point load system that utilizes a central load on a simple support beam as a test method.

The test parameters are as follows.
Support span (L) = 40mm
Radius of rotatable material support member = 10mm
Load nose radius = 5 mm
Crosshead operating rate (R) = 20 mm / min Deviation = 10 mm

The test sample used was
(E) Easyflex 50mm ostomy coupling plate with ostomy pouch which is an attachment coupling manufactured by Coroplast A / S. (M) Ostomy pouch which is a mechanical coupling manufactured by Coroplast A / S. MC2002 50mm ostomy coupling plate with (20) 24200 45mm ostomy coupling plate with ostomy pouch which is a mechanical coupling manufactured by Hollister

  As can be seen from the table, the bending force for the attachment coupling is less than one tenth that of the mechanical coupling, thus providing much better flexibility for the coupling and allowing the user to sit Or allow the body to follow the body when lying down. Otherwise, pressure will be applied to the body.

  Thus, it can be appreciated that a flexible coupling plate can provide a relative flexible coupling when coupled with a corresponding flexible coupling plate. In one embodiment, such flexibility can thus be defined by a bending force at 10 mm excursion relative to the combination coupling, and in one embodiment, the bending force is less than 10 N for 10 mm excursion. Yes, preferably less than 6N for 10 mm excursion, and especially 4.5N for 10 mm excursion.
